how to calculate the lognormal distribution in matlab

To calculate the lognormal distribution in MATLAB, you can use the 'lognpdf' function. The 'lognpdf' function computes the probability density value for a given set of parameters and x-values. The parameters required for computing the lognormal distribution are the mean and standard deviation of the associated normal distribution.

Here's an example code block illustrating how to calculate the lognormal distribution for a given set of parameters:

main.m
% Define the mean and standard deviation values for the associated normal distribution
mu = 2;
sigma = 0.5;

% Define a set of x-values at which to compute the lognormal distribution
xValues = linspace(0, 5, 100);

% Calculate the lognormal distribution
pdfValues = lognpdf(xValues, mu, sigma);

% Plot the lognormal distribution
figure();
plot(xValues, pdfValues, 'LineWidth', 2);
xlabel('X Values');
ylabel('PDF Values');
title('Lognormal Distribution');

This code block will produce a plot of the lognormal distribution, with the x-axis ranging from 0 to 5 and the y-axis representing the probability density values.
